Emmerdale airs a reunion for exes Tracy Metcalfe and Nate Robinson next week, as the pair give into passion despite being with other people.
Tracy recently revealed she was dating someone knew, leaving Nate gutted - but it seems she's hiding an even bigger secret.
A few weeks ago, Nate began a new romance with Naomi Walters - but both Tracy and Nate realise next week they still have feelings for each other.
In upcoming scenes on the ITV soap, the pair give into temptation after Tracy arrives with their daughter Frankie.
Tracy fails to share her big news with Nate though, with it confirmed she is engaged to her new partner Ollie.
As she decides to break the news to him things get heated, and soon the pair become intimate and end up sleeping together.
They're caught out though despite Tracy's efforts to conceal the moment of passion, even kicking Nate out of the house in nothing but his boxers.
Tracy's sister Vanessa learns the truth though when she finds Nate's phone and clothes, and her suspicions are confirmed when Nate returns to collect his possessions.
Vanessa despairs when Tracy later confesses she still likes Nate despite her blossoming romance with Ollie, and their engagement.
Of course Ollie and Naomi have no idea about the betrayal for the time being, but will Tracy and Nate get back together?
Actress Amy Walsh recently spilled all on her brief comeback, ahead of a permanent return later down the line.
Amy welcomed her baby daughter Bonnie in December last year with her partner Toby-Alexander Smith.
Tracy left the village in scenes that aired in January, and she will return for the first time this week ahead of the soap's special episodes.
She spilled: "It was lovely to be invited back for the 50th. When I was going on maternity leave Jane (Hudson), the executive producer, mentioned it was all happening around August and September and said if I wanted to be a part of it to let her know but when it came to it I just wasn’t ready to come back full time.
"She very kindly offered to write me in and back out again so I didn’t have to cut my maternity leave short but I still didn’t miss out on the 50th celebrations so it was win-win!"
Emmerdale airs weeknights at 7:30pm on ITV, with an hour-long episode on Thursdays.
